During the COVID-19, how should we disinfect our clothes every time we go out? What is a safer way to do it?
The probability of the virus infecting people by contaminating clothing is extremely low, and the general public does not need special disinfection of clothing unless they have been to a specific place (such as visiting a hospital, visiting a patient, or being in contact with someone with suspicious symptoms).
Alcohol has no corrosive effect on ordinary clothes, but alcohol is a Class A flammable item. If it is sprayed on clothes, it may catch fire when encountering high temperature, open flame, and static electricity. Therefore, it is recommended not to spray alcohol on clothes.
Directly spraying clothes with chemical disinfectant will also cause irritation and damage to people. At the same time, because the spraying time is too short and the amount of spraying is too small, the disinfection effect will not be achieved.
The daily clothes can be hung at the door after going out and returning home. It is enough to separate the clothes you wear outside from the clothes you wear at home, and you don’t need to disinfect it every time.
If you feel that the coat may be contaminated (for example, you have been to the hospital, visited patients, etc.), you need to disinfect the coat, first of all, you should try to use physical disinfection. If physical disinfection is not applicable, chemical disinfection can be used.
If the clothes are high temperature resistant fabrics, they can be washed with 56℃ water temperature for 30 minutes. If there is a dryer, the temperature can also be adjusted to above 80℃, and drying for 20 minutes can also achieve disinfection.
By looking at the durability label of the clothing, you can judge whether the clothing is suitable for high temperature disinfection. The sink symbol on the label is the wash symbol, and the number in it represents the maximum allowable wash temperature for the item.
To use dry sterilization, you need to pay attention to the flip dry symbol on the label. If there are 2 dots in the circle of the symbol, it means that the drying temperature of 80℃ is acceptable.
For clothing that is not resistant to high temperature, chemical disinfectants can be used to soak and disinfect.
Common disinfectants include phenolic disinfectants, quaternary ammonium salts disinfectants, and chlorine-containing disinfectants represented by 84 disinfectant. All three types of disinfectants can be used for clothing disinfection, but they must be operated according to the dosage of the instructions.
These three disinfectants also have their own shortcomings, so be careful when using them. Phenolic disinfectants sometimes stain synthetic fiber materials, which may discolor them. Chlorine-containing disinfectants such as 84 disinfectant may have a fading effect on clothing and will bleach. Quaternary ammonium salt disinfectants, if used together with anionic surfactants such as washing powder and soap, will fail on both sides, neither disinfecting nor cleaning. Therefore, the disinfectant should be selected according to the actual situation.
